undefined method `tap' for #<Rails::Server:0x15d8ea4> (NoMethodError)

#4606

I'm on Mac 10.5

Here are my steps.

rvm install 1.9.2-head
rvm use 1.9.2-head
gem install rails --pre
rails newapp
updated my Gemfile to have:

 gem "rails", :git => 'git://github.com/rails/rails.git'  # (or)
 gem "rails", :path => '/path/to/clone/of/[git://github.com/rails/rails.git]' # (both gave same error)

bundle install
rails server

here's the error

/Users/fl/.rvm/gems/ruby-1.9.2-head/gems/rack-1.1.0/lib/rack/server.rb:170: warning: parenthesize argument(s) for future version
/Users/fl/.rvm/gems/ruby-1.9.2-head/bundler/gems/rails-16a5e918a06649ffac24fd5873b875daf66212ad-master/railties/lib/rails/commands.rb:27: undefined method tap' for #&lt;Rails::Server:0x15d8ea4&gt; (NoMethodError)

Wait, are you specifying a path to a clone in your gemfile? like this:
```
  gem 'rails', :git => '~/code/rails'
```
Bundler's :git option ( http://gembundler.com/git.html ) expects a git repo to clone from. If you want to specify a path, use the :path option, like this:
```
  gem 'rails', :path => '~/code/rails'
```
Or am I completely missing the point? :)

My bad, it was an oversight on my part. I updated the code accordingly.

Fixed, if you have this error, do...
```
rvm use system
rvn use 1.9.2-head
```
switching out of the ruby version, then back into it clears up the issue.
